Watching Mom And Dad

My sexual awakening happen when I was about 15 I was at a friend's house when his sister was involved in an accident so they dropped me off at home around ten that night. I walked in and noticed that my mom and dad were having sex on the couch in the living room. They had not heard me coming in and mom was in the doggie style position and dad was really fucking her hard. She was moaning and telling him to pound her pussy harder. About that he told her he was cumming as he finished cumming and pulled out I could see mom's stretched open pussy with cum leaking out. He then picked up this huge dido that look to be at least 12 to 13 inches long and about the size of my arm around and started pounding her pussy with it. In no time at all she was moaning she was having one. My mom then stood up and walked over and told my dad to bedroom to have a little more fun. I went to my room and begin jacking off I came like never before. After that night I made it my mission to catch them in the act it took a couple of weeks before I got a chance to see them again.
It had all started as a normal Saturday with mom going shopping while dad and I worked in the yard. By mid afternoon I had made plans with some friends to go to the movies and mom and dad were planning on going out to eat. I got home around ten and mom and dad still were so I went on to my bedroom planning on jacking off before anyone got home. I had just started good when I heard the two of them come in and go thru the house around to the pool area. I slipped out of my room and looked out the window and my dad was removing my mother's clothes and she was soon standing naked out be the pool. I then saw something and could not believe my eyes there was another younger guy with them and he was about to be licking my mom's cunt. As I stood watching my dad sat down in a chair by the pool watching my mom and this guy go at it. He licked her and then she undid his pants and released a very large cock and began sucking on it. It was not long and the guy pulled out of her mouth and bent her over a chair and fucked her doggie style with this monster of a cock. It seemed as if he pounded her pussy for thirty minutes before he finally shot his load into her pussy. As he pulled his cock out of her pussy I could see that he had really left a large load of cum inside her pussy and it was running down her leg. My dad went to her and began licking her cum soaked pussy and my mom began sucking on this guy cock. In no time at all he was hard again he sat down in a chair and my mom straddle him and was riding his cock my dad walk up behind them and began putting his cock into her ass. My mom was moaning and telling them both to fill her with cum. My dad came first filling her ass with cum and then the other guy came mom had cum leaking out of her big time. The other guy said his good nights and left and mom and dad came in the house mom still leaking cum onto the floor.
